| <section name="Welcome to Apache HBase™"> |
| <p><a href="https://www.apache.org/">Apache</a> HBase™ is the <a href="https://hadoop.apache.org/">Hadoop</a> database, a distributed, scalable, big data store.</p> |
| <p>Use Apache HBase™ when you need random, realtime read/write access to your Big Data. |
| This project's goal is the hosting of very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. |
| Apache HBase is an open-source, distributed, versioned, non-relational database modeled after Google's <a href="https://research.google.com/archive/bigtable.html">Bigtable: A Distributed Storage System for Structured Data</a> by Chang et al. |
| Just as Bigtable leverages the distributed data storage provided by the Google File System, Apache HBase provides Bigtable-like capabilities on top of Hadoop and HDFS. |
